1. Apparatus for controlling activation and deactivation of a motor for moving a motor vehicle mounted window, panel or door along a travel path comprising:

  • a) a noncontact electric field sensor for monitoring a region in proximity to the window, panel, or door and sensing changes in electric field due to dielectric properties of an object in the region;

    b) a switch for controlling energization and de-energization of the motor with an energization signal; and

    c) a controller coupled to the switch for controllably energizing and de-energizing the motor and having an interface coupling the controller to the non-contact electric field sensor;

    d) said controller comprising a programmable controller including a memory for storing instructions for executing a control program to control an operating state of the motor in response to the non-contact electric field sensor sensing an object in the region in proximity to the window, panel, or door.
